"real" and "floating point" are different things... we CAN do exact
arithmetic with reals; consider that any real number must be the result of
an expression, such as "root 2" or "pi", so you can just store it as the
expression and do everything with symbolic manipulations!
"real" is something in the mathematical domain, "floating point" is one
(approximate) implementation of "real", and a poor one at that!
